A loaded microservice applications for doing different kinds of POC. This is a sample Employee System which is designed to understand the microservices nature and behaviour.
The purpose of creating this application is to provide an individual, a holistic idea of microservice architecture, it's working, and its setup.
These are few microservices which are getting used in this complete project.

The architecture of the complete microservice interaction looks like this:-
The quickstart of application can be started using docker and docker-compose. We can use simple docker-compose command to build the images and start the setup.
# To build the all images of ot-microservices
make build-images
# To start the setup locally
make setupFor further details checkout GETTING_STARTED
